Objective: To optimize flash extraction process of active components from Eucommiae Folium. Method: HPLC was employed to determine contents of chlorogenic acid and geniposidic acid with mobile phase of methanol-water-glacial acetic acid(15: 85: 1)
flow rate of 1.0 mL·min-1 and detection wavelength at 237 nm.Taking yields of chlorogenic acid and geniposidic acid as index
based on single factor tests
orthogonal test was adopted to optimize extraction process with ethanol concentration
liquid-solid ratio
extracting time and times as factors. Result: Optimal process conditions were as follows:extracted thrice with 25 times the amount of 70% ethanol for 6 min each time;yields of chlorogenic acid and geniposidic acid were 1.82% and 0.47%
respectively. Conclusion: This optimized process is simple
accurate and suitable for extracting active ingredients from Eucommiae Folium.
